Product details
Overview
P6KE200ARL from STMicroelectronics is a unidirectional 600 W transient voltage suppression diode in DO-15 package, designed for primary-level surge protection in DC power rails and signal lines. It features a 200 V breakdown voltage (VBR = 190–210 V), 274 V clamping voltage at 2.2 A (10/1000 µs), 0.5 µA max reverse leakage at 171 V, 175 °C max junction temperature, and complies with IEC 61000-4-2 (30 kV contact/air) and IEC 61000-4-4 (4 kV level 4).
For engineers reviewing the P6KE200ARL datasheet, P6KE200ARL pinout, P6KE200ARL application, or P6KE200ARL equivalent, this page delivers verified electrical parameters, thermal derating behavior, DO-15 terminal mapping, real-world ESD/surge protection use cases, and validated alternative parts with documented functional differences.
Technical Context
The P6KE200ARL operates as a silicon avalanche diode that enters controlled breakdown above its 200 V nominal VBR, limiting transient voltages to ≤274 V at 2.2 A (10/1000 µs). Its planar junction structure enables low leakage (<0.5 µA at VRM = 171 V) and stable performance up to 175 °C junction temperature.
It supports both 10/1000 µs (600 W) and 8/20 µs (up to 4 kW) surge waveforms, with dynamic resistance of 12.7 Ω at 10/1000 µs and 10.8 × 10−4/°C temperature coefficient for VBR drift - enabling accurate clamping prediction across operating temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 190 / 200 / 210 V - defines precise voltage threshold at which avalanche conduction begins under 1 mA test current |
| VCL @ IPP = 2.2 A | 274 V - maximum clamped voltage during 10/1000 µs surge, directly limiting stress on downstream ICs |
| IRM @ VRM = 171 V | 0.5 µA - ultra-low reverse leakage ensures minimal standby power loss in high-impedance circuits |
| Tj max | 175 °C - enables reliable operation in enclosed industrial enclosures or near heat-generating components |
| PPP (10/1000 µs) | 600 W - peak pulse power rating used to size TVS for common lightning-induced surges per IEC 61000-4-5 |
| αT (VBR) | 10.8 × 10−4/°C - quantifies VBR shift with temperature, critical for clamping margin calculation at elevated Tj |
| RD | 12.7 Ω - dynamic resistance determines voltage rise above VBR under surge current (ΔV = RD × IPP) |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with cathode band marking. Body length: 6.05–6.75 mm; lead diameter: 0.71–0.88 mm; overall length: 26–31 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point during forward conduction | Connected to protected line when used in unidirectional configuration; must be tied to ground or lower-potential rail |
| Cathode (banded end) | Avalanche conduction node during reverse overvoltage | Connected to protected line; clamps transients to VCL relative to anode reference |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD immunity | 30 kV air/contact discharge - exceeds Level 4, eliminating need for external ESD filters in front-end interfaces |
| High-temperature stability | Rated to 175 °C junction - maintains clamping performance in automotive engine bay or industrial motor drive environments |
| Low dynamic resistance | 12.7 Ω at 10/1000 µs - minimizes overshoot during fast-rising transients, improving protection margin for sensitive logic |
| Planar junction construction | Enables <0.5 µA leakage at 171 V - suitable for battery-powered systems where quiescent current impacts runtime |
| UL 497B certification | QVGQ2.E136224 - validates suitability for telecom/data line surge protection per UL safety standards |
Applications
| Industrial PLC I/O Protection | DC Power Input Stage |
|---|---|
Use Scenario: 24 V DC input terminals on programmable logic controllers exposed to induced surges from relay switching or nearby AC mains. IC Role / Device Role / Timing Role: Primary shunt protector placed before upstream DC-DC converter and microcontroller power domain. Use Value: Clamps 1 kV/0.5 A surge (per IEC 61000-4-4) to ≤274 V, preventing latch-up or permanent damage to 3.3 V/5 V logic supplies. | Use Scenario: 48 V telecom power supply input subjected to lightning-induced longitudinal surges on outdoor cable runs. IC Role / Device Role / Timing Role: First-line transient suppressor mounted at connector entry point, ahead of bulk capacitance and EMI filter. Use Value: Absorbs 600 W (10/1000 µs) energy without degradation, maintaining system uptime in harsh field deployments. |
| Automotive Body Control Module | RS-485 Communication Line |
Use Scenario: LIN bus or sensor supply lines in vehicle body control units subject to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS tied between 12 V rail and chassis ground, suppressing positive-going transients only. Use Value: Withstands 175 °C ambient under hood conditions while delivering consistent 274 V clamping, ensuring CAN/LIN signal integrity. | Use Scenario: Termination points of long-haul RS-485 data links in factory automation, vulnerable to ESD and ground potential differences. IC Role / Device Role / Timing Role: Bidirectional protection (P6KE200CA variant) placed across differential pair, referenced to local ground. Use Value: 30 kV ESD tolerance prevents communication lockup during operator handling; low CJ (~100 pF at 1 V) avoids signal edge degradation at 10 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same VBR (190–210 V), but SMC package (higher thermal mass); 600 W rating at 25 °C, derates faster above 85 °C | Preferred for higher-volume automated assembly due to surface-mount footprint; less suited for through-hole legacy designs | Select SMBJ200A if PCB layout allows SMD placement and thermal management uses copper pour; retain P6KE200ARL for axial-leaded serviceability or high-reliability through-hole builds |
| 1.5KE200A | Same DO-15 package and VBR, but 1500 W peak power (10/1000 µs); higher IPP (6.9 A) and VCL (328 V) | Better for severe surge environments (e.g., outdoor utility meters), but higher clamping increases risk to downstream 3.3 V ICs | Choose 1.5KE200A only when surge threat exceeds IEC 61000-4-5 Class 3; otherwise P6KE200ARL's lower VCL provides tighter protection margin |
Compared with SMBJ200A and 1.5KE200A, P6KE200ARL offers optimal balance of low clamping voltage (274 V), axial-leaded mechanical robustness, and 175 °C thermal capability - making it ideal for space-constrained industrial controls where reliability trumps raw power rating.

FAQ
What is the maximum clamping voltage of P6KE200ARL under a 10/1000 µs surge?
The maximum clamping voltage (VCL) is 274 V at 2.2 A peak pulse current for the 10/1000 µs waveform. This value is measured at Tamb = 25 °C and represents the upper limit of voltage seen by downstream circuitry during standardized surge testing per IEC 61000-4-5.
Can P6KE200ARL be used in bidirectional signal line protection?
No - P6KE200ARL is unidirectional and must be connected with cathode to the protected line and anode to ground. For bidirectional protection (e.g., RS-485), use the P6KE200CA variant, which has symmetrical breakdown in both polarities and identical VBR/VCL ratings.
How does junction temperature affect the breakdown voltage?
VBR shifts with temperature at +10.8 × 10−4/°C. At 125 °C, VBR increases by ~1.08% over its 25 °C value (i.e., 200 V → ~202.2 V), ensuring predictable clamping margin even in high-temperature environments like motor drives or under-hood automotive modules.
Is P6KE200ARL RoHS-compliant and halogen-free?
Yes - P6KE200ARL meets RoHS Directive 2011/65/EU and is halogen-free per STMicroelectronics' ECOPACK2 specifications. The matte tin-plated leads comply with J-STD-002 and JESD22-B102 E3, and the device carries UL 497B certification (QVGQ2.E136224) for safety-critical applications.
